In the wake of the Obama administration’s plan to decrease antibiotic usage in livestock, farmers are now trying to find alternatives that have fewer ecological and human health impacts. In an effort to reduce reliance on antibiotics, researchers at Iowa State University are testing if Lactobacillus species found in yogurt might have a similar health effect on livestock as …

I’ve been seeing a lot of media articles recently on applications of gut microbiome research in health in terms of pills and probiotics. One article talks about a start-up that is trying to create various pills filled with bacteria associated with different positive health effects. Of course, there is the question if such probiotics will thrive in …

Perhaps you’ve heard about Dr. Premsyl Bercik’s recent publication in Nature Communications about the link between the gut microbiome and mental disorders such as depression and anxiety disorder. In his study, he induced early life stress in conventional mice and in germ-free mice by separating new born pups from their mother for several hours a …

Just a quick post here on an NPR story that caught my attention “Giving Chickens Bacteria … To Keep Them Antibiotic-Free”. Unlike with humans where determining the effect of probiotics is complicated by a lot of variation in the population (genetic, cultural, diet, etc.), with a whole bunch of chickens it’s easier to measure the …

Researchers in Egypt did a fascinating study recently on probiotics for fish. They tested the effect of three different types of Psuedomonas fluorescens on two pathogens that affect tilapia in the Nile (P. angulliseptica and S. faecium). Their aim was to find a more eco-friendly way of controlling the pathogens in aquaculture compared to chemical antimicrobials. The probiotic was indeed …

Microbiology is on a roll, it’s been an amazing couple decades of discoveries that have transformed our understanding of the roles that microbes play in human health. And this knowledge has pushed its way into popular culture. Every couple of days I see another popular media article about the influence of microbes on something else; …

I guess I would call myself a microbe beginner. I recently joined Dr. Eisen’s lab and I am getting up to speed on studying, sampling, and understanding microbial communities, especially in the built environment. Now I think about microbes ALL OF THE TIME. On every surface, in the air, on every inch of my body. …

Just a quick post to point out an article on phys.org talking about Amy Pruden’s fascinating work on probiotics for plumbing. Read her microBEnet post about the work here and a related post by Kyle Bibby here. From the phys.org article: “We believe this microbiome can be harnessed to control opportunistic pathogens,” Pruden said. For …

Hats off to Tuesday’s New York Times article, “A Quest for Even Safer Drinking Water,” for daring to bring microbiology to the people. The article sheds light several key reasons we can no longer afford to ignore the vast microbial diversity that exists within the drinking water environment, among them are opportunistic pathogens and antibiotic …

We’ve recently received an award from the Sloan Foundation to examine the mycobiota from paired house dust and infant fecal samples collected in the first year of life. The main purpose of the study is to examine how the immediate environment (house dust) may shape the gut mycobiota of infants and affect immune activation and …
